ARBALEST: Dynamic Detection of Data Mapping Issues in Heterogeneous OpenMP Applications
2021 IEEE International Parallel and Distributed Processing Symposium (IPDPS)（2021）
摘要
From OpenMP 4.0 onwards, programmers can offload code regions to accelerators by using the target offloading feature. However, incorrect usage of target offloading constructs may incur data mapping issues. A data mapping issue occurs when the host fails to observe updates on the accelerator or vice versa. It may further lead to multiple memory issues such as use of uninitialized memory, use of sta...
